Until that check is complete for this page, read the exact wording directly from the official source linked below — it is the only version that governs.
The authority is the enacted text, not this page. Where our wording and the official provision, or an applicable Gazette notification, do not match, the official material prevails.
What this rule requires, step by step
Patent disputes turn on technology. A judge hearing a case about a catalytic process, a gene construct or a signal-processing algorithm may need help understanding what the technology actually does. Section 115 of the Patents Act, 1970 allows a court, in a suit for infringement or other proceedings under the Act, to appoint an independent scientific adviser to assist it or to inquire into and report on a question of fact or opinion that the court frames. The adviser does not decide the case and does not interpret the law; the adviser explains the science.
So that courts are not left searching for an expert at short notice, section 115 also provides for a roll of scientific advisers to be maintained. Rule 103 gives that roll its shape. It sets out what the roll contains for each person listed, typically the name, address, nationality, academic and professional qualifications, and the field of science, engineering or technology in which the person has expertise. A court can pick an adviser from the roll, although the section does not force it to choose only from the roll.
The rule also fixes who is eligible. Broadly, a person needs a degree in science, engineering, technology or an equivalent qualification, substantial practical or research experience in the field, and standing in that field, usually demonstrated by having held a responsible position in a scientific or technical organisation. The Rules state the exact number of years of experience required, and that figure has been set at fifteen years, so any reader planning an application should confirm the current requirement against the latest text of the Rules before applying.
For litigants, the roll matters because it shapes who might be appointed in their case. A well-populated roll in a niche field, say pharmaceutical formulation or embedded electronics, makes it easier for a court to find someone who genuinely understands the patent. A thin roll increases the chance that the court will look outside it or lean more heavily on the parties' own experts, whose independence is naturally open to challenge.
For scientists and engineers, inclusion in the roll is a form of public service and professional recognition. It does not create employment or guarantee any appointment, and there is no entitlement to be picked in any particular case.
Why this rule matters
Senior scientists, engineers and technologists who wish to be listed, and parties to patent litigation who may face a court-appointed adviser.
Before litigation, when the roll is built and maintained, and during litigation, when a court decides whether to appoint an adviser.
A standing panel of qualified independent experts, and eligibility standards that a person must meet to be listed.
If the roll is thin in a technology area, courts have less independent technical help and cases can turn on partisan expert evidence.
How it works in practice
A court looks for someone who understands membranes
Neelkanth Membranes Ltd sued a Surat manufacturer for infringing its patent on a hollow-fibre membrane module. The two sides filed expert affidavits that flatly contradicted each other on whether the defendant's fibre spinning process produced the pore structure described in the claims. The judge decided that an independent voice would help and framed a narrow question: whether the defendant's product, on the agreed test data, showed the claimed pore-size distribution. The court turned to the roll of scientific advisers maintained under section 115 and Rule 103, and found Dr Ananya Rao, a polymer scientist with a doctorate in membrane technology, more than two decades of laboratory and plant experience, and a senior post at a national research institute, listed for exactly that field. She was appointed to inquire and report on the framed question only. Her report explained the test method and what the data did and did not show, and left the questions of claim construction and infringement entirely to the court.

Key points to remember
- Section 115 lets a court appoint an independent scientific adviser to help it understand technical questions in patent proceedings.
- Rule 103 provides for the roll of scientific advisers and the particulars recorded in it.
- Eligibility rests on a science, engineering or technology qualification, long practical or research experience, and standing in the field.
- The exact years of experience are set by the Rules and should be checked against the current text before applying.
- An adviser reports on facts and technical opinion, never on questions of law or claim interpretation.
- A court may appoint someone from the roll, but is not limited to the roll.
Common mistakes and misunderstandings
- Confusing a scientific adviser with an expert witness engaged by a party. The adviser assists the court and is expected to be independent of both sides.
- Assuming the adviser decides infringement or validity. Those remain matters for the court.
- Thinking a listed adviser is guaranteed appointments or paid a retainer. Listing only records availability and credentials.
- Treating the roll as the only source of technical help; a court may look beyond it if no listed person fits the technology.

This page explains a rule of the Patents Rules, 2003. A rule does not stand on its own; it works out a duty or a power that the Patents Act, 1970 has already created. The parent sections are listed separately so you can read the source of that authority.
Forms, deadlines and fees
Where a fee is payable under this provision, the figure comes from the First Schedule. Categories of applicant are charged at different rates, and electronic filing is treated differently from paper filing, so an accurate number can only come from the Schedule in force on the day you file.

Questions people ask about Rule 103
What does a scientific adviser actually do in a patent case?
The adviser helps the court with technology, on the terms the court sets. A court may ask the adviser to sit in and explain technical evidence as it is given, or to inquire into a specific question of fact or technical opinion and file a report. The court frames the question. The adviser must stay on the technical side of the line: how a process works, what a test result shows, what a person skilled in the field would understand a term to mean in practice. Legal conclusions belong to the judge.
Who maintains the roll of scientific advisers?
The roll is maintained under the authority of the Central Government through the Patent Office, and Rule 103 governs what it contains and who qualifies for inclusion. In practice, applications from scientists and technologists are processed by the Patent Office and the roll is kept as an official record listing each adviser's field, qualifications and experience. Courts hearing patent matters can consult it when they decide that independent technical assistance would help them decide the case.
Can a party object to the adviser the court appoints?
A party can bring genuine concerns to the court's attention, for example that the proposed adviser has consulted for the opposite side, holds a competing patent, or works in an organisation with a commercial stake in the outcome. Independence is the whole point of the appointment, so courts take conflict objections seriously. What a party cannot do is object merely because it fears the adviser's report will be unhelpful. Objections should be raised early, with specifics, not saved until after the report arrives.
Does being on the roll help my career as a scientist?
Inclusion is a recognition of expertise and independence, and being consulted by a court is a serious professional responsibility. But it is not a job, there is no guarantee of any appointment, and it should not be described as an official position in the Patent Office. Anyone considering it should also think about conflicts, because a person who regularly gives paid expert evidence for one side of the industry may find it hard to be seen as independent.
